Fake text messages are showing up in workplace investigations, and real messages could be denied as deepfakes. In this video: why the receipts that used to settle misconduct cases stopped settling anything, and what proof looks like now.
Can a screenshot still prove workplace harassment? A digital forensics expert on why cases that never needed forensics now depend on the device behind the message.

Text message screenshots are unreliable as legal evidence. Easily faked even before generative AI.
Metadata was never proof. It is an envelope written in pencil, and every new app and upload pipeline hands someone else an eraser.
A digital forensics expert on why screenshots of text messages prove almost nothing, what carrier records and backups miss and when only the smartphone can answer.
"It wasn't me. My AI did it." That defense is coming, and the way AI agents work right now, it might hold up. Ovie Carroll, SANS instructor and career federal cybercrime investigator, ran the test that shows why: an AI agent edited a Word document and left none of the records that usually show a per
'It wasn't me. The agent did it.' AI agents can use a computer like a ghost or just like you. A digital forensics expert on proving whether you or the AI touched the file.
GenAI has ruined trust because anyone can make fraudulent media (like photos, videos, audio) with little to no technical skill or cost.
A police officer allegedly used AI to fabricate evidence. The deeper problem is that no one kept the original recording to catch it. Here is the fix.
Why catching deepfake video calls belongs on your device—not in the cloud.
